Capturing Heat from Freezer Compresors

01/19/2010 6:26 PM

I am seeking information on heat recovery systems for multiple freezers in a dept. store setting. I am new at the whole topic but have been asked to look into it for someone even less computor savy than myself. The store has about 20 freezer type compressors.Air conditioning units are also evident so I guess that too is relavent.

I did look into a few sites but they were very complex to me are there any sites that I might do better in? Thank you Denton,Dawson Creek B.C. Canada

When you say heat recovery are you intending to use that heat to suppliment the building heating costs? or are you trying to heat another fluid??

Sorry, but as a practicing mechanical engineer in BC, I'd have to say based on the content of your post alone, you are over your head. And, you are likely not experienced enough to be able to understand the finer details and costs associated with the decisions you need to make to finalize a design.

I doubt you will get what you are looking for on any website, as I said this needs to be designed and each installation is unique in that the results from calculations, the power costs, the built environment and the climate will result in a different answer for each installation.

This is what people hire professionals to do, and you are dealing with a complex system. Why would I give my hard won knowledge and experience away to a commercial enterprise?

As I understand from your post, you are in the wrong area mate and the one who has asked you to 'look into' is also unclear as to what can be expected from you.

Heating and cooling is a complex system and if you like to take help of sites, since you claim to computer savvy, I suggest you start from the basics of Thermodynamics.

Hello Denton,

DaS Energy has published work that is right up your alley, and it is completely free. The heat from a electric compressor goes to heat liquid supplying a recycling hydro turbine/generator. Using this method heat from one electric compressor is enough to drive many DaS powered turbine generators. This equipment is not off the shelf available but should you have the Kw draw of each compressor the rest is easy to calculate. I can walk you thriugh the design privately or via this site.

Blueprint wont cut and paste to this site.

Cheers Peter

Do not give up on recovering the heat. These engineers are using double talk with their "too complex for a non engineer" bs. The compressors give off heat and your job is to get it away from there and duct it to where the heat is needed. Use the shortest route possible and try ventex.com Remember , an engineer will tell you anybody can do a job when it will benefit them but when it comes to saving engineering fees ,no one is capable, hence the double standard.

LOL... well you get what you pay for. When it all goes wrong and does not work who will they call? I have seen this many times, a salesman tells someone not to talk to an engineer... why pay them when you can pay me? That's what your comment is about.

Saving energy is a fantastic idea. I have designed many systems which meet or exceed LEED criteria. Heat pump systems using closed and open loop designs, waste heat recovery, etc. In the past I wish more clients had looked beyond first costs and included life-cycle costs into their purchasing decisions. Fortunately, more are now considering these factors.

So, anyway in this matter...How will the proposed system tie into the existing systems? How will the controls work? What happens to the waste heat when the store requires cooling? Can the heating plant be be reduced in size? How will this be piped? What are the maintenance procedures? What are the savings, payback period and benefits? What are the other impacts, including space and access requirements, structural loading, seismic restraint, electrical provisions? What are the other options? How much will this cost? What is the warranty?

An engineer is responsible to the work, carries a duty, ethics and legal responsibility which extends beyond a single product or its warranty. A disreputable salesperson who advises a customer not to talk to an engineer cannot be trusted. There are good salespeople out there that I have worked with, and they sell the engineer first. If the procedure or product cannot bear up to critical scrutiny... well you get the point.

Hmmm, all double talk, right. As I said, I've seen it before, its not pretty, and its way more costly to fix something later than to do it right the first time. As the saying goes... you can pay me now or you can pay me later.

your friendly neighbourhood engineer

Not sure of exact spot any more but its in CR4. Also web search Das Energy, or DaS Turbine should bring it up.

In attachment of Open Letter no.9, transmitted to many scientists, it is shown technical procedure and experiment where the heat is captured from air and converted directly into cold, as an active solution against global warming, and a possible new source of energy in the future.

(* Attachment: 2. A NEW ACCESSIBLE SOURCE OF ENERGY?

A cubic meter of air from a wind speed of 15 m / s, hitting a wind turbine blades, it may give an energy below 100 J, while the thermo-kinetic energy of air molecules in the same amount of stationary moving at a internal kinetic speed of 343 m/s, is over 500 times.

Just find ways to extract only 1% of internal air thermal-kinetic energy to overcome than 5 times the energy produced today from all wind farms in the world.

Idea is based on two observations:

a)- energy transferred by air wind to turbine blades is the vectorial component (into translation movement) of the total energy of the air mass, while the thermo-kinetic energy of stationary air is full scalar component;

b)- experimental research was stimulated by Bernoulli measurements, where it was found that the volume of air circulated by serial two tubes, one with dual section over the other, gets double the speed in the tube having the lower section compared to the tube having large section ( satisfying the equations of continuity of flow and energy).

Increase vectorial component of energy of 4 times in thin tube compared to the same component in the gross tube (for the same amount of air), can be explained only on account of thermal-kinetic energy decrease with an equivalent amount of energy.

This claim was validated experimentally by installing thermometers and anemometers within two serial tubes, where the air circulated by a fan, was significantly cooled in lower section than in large section. Calculations based on measurement results confirmed the equivalence of thermal-kinetic energy lost by cooling in the lower section, to the supplementary vectorial energy (the translation movement) expressed by the formula:

ΔE = 3ma.v2 / 2, (10)

where ma is the mass of air that traverses both tubes in the same period of time.

And other researchers tested the idea along time, aims to create a technology that can extract part of the supplementary energy ΔE, in terms of yield overall positive, yet unattainable goal for someone to date. All previous experiences have been based on introducing additional turbine in tube of small section and collect an usable momentum in that axis turbines. The failures were due to the fact that every time the power consumed by the fan increases more than the collective power to further the turbine axis, the overall efficiency of the system is always negative.

Remaking those experiences, the author of this communication has found that air cools itself along the pipeline thin, but is close to the original temperature immediately after entrance into the large section.

The conclusion was that thermal dipole of thermodynamic theory is formed only in the area of transition from tube to tube thin-large, so additional turbine to be located in that area to achieve an extract that power solely to the dipole thermodynamically. This was proved experimentally by simultaneous measurement of temperature before and behind the supplementary turbine located immediately out of thin tube and the change of power absorbed by the fan.

The air remained cold and after passing additional turbine and power / current absorbed by the fan from has remained virtually constant in the two situations: the system with additional turbine and turbine system without additional.

An additional mechanical power at turbine axis has been obtained solely to the thermal kinetic energy of air (without increasing consumption in fan). Practically it obtained a first air cooler without supplementary circuit of condensation and without electricity use for.

A second stage experience was the addition of a rotor with blades, instead of separate additional turbine along the shaft of the fan (extended behind the fan shaft), with direction "antiventilation" (as opposed to the orientation of the fan's blades), so that the rotor antiventilation ( which opposes to penetration of fluid-air) is rotated in the same direction with the rotor fan, because, as the axis of joint involvement and action to impact air antiventilation blades.

The new situation has been a significant decrease of fan power absorbed, compared to the situation without supplementary rotor, at the same debit of air evacuated.

Another stage experience was to repeat the experience of the previous phase, but install the fan more powerful, able to increase air speed in the tube than to over 100 m / s, in which appeared the phenomenon of "kinetic tornado" where rotation unplugged the fan and air circulation is self-keeping and exhaust air cools more.

Thus obtain a cooler anti-global-warming shown schematically in the Fig.1, which works without electricity use, just on account of the heat in the atmosphere.

Currently experiments are continued to obtain additional electric power, cooling simultaneously with anti-global warming, under self-financing circumstances extremely precarious. We do our courage with the thought that at the researchers, the hope is the last parting together its bearer.

Open Letter No.9: Call to all scientists to propose / support concrete actions to correct the fundamental error reported, both in research and in the education, on the occasion of ESOF (Euroscience Open Forum) Torino, Italy, on 2-7 July 2010.


Dear Mr. Prof. GERARDUS 'T HOOFT,
From your works and your comments on letter No. 8, I understand that you so far have not had the chance to know the new physics of corpuscular-wave spaces, because of censorship practiced by the paper-journals that you have access.
Without information about new research results, I fear that you will understand with difficulty differences between the Physics Corpuscular-Wave Quantum Space and imaginary Geometrical Space, in that you placed fixed and mobile referentials with respect to the observer phenomena.
With all my admiration for your quality of Nobel Prize winner, still try to give you some benchmarks, which I hope will be useful in your research, for which I wish entire success.

1. Quantum Space has both corpuscular and wave parts. All research results confirm that corpuscular part is under form of photons and elementary particles (kinetic pulsatile clusters), and wave part is under form of kinetic wave composed by free "elementary quantum particles" (undiscernible individual particles) with mass mc = ĥ /c^2, and c translation speed, which inhabit Quantum inter-particle Space, where Planck's constant h, is corpuscularly expressed in J, not J.s.

Using here the wave expression of the constant h is eroneous, as it leads to the expression the mass mc = h/c^2=7.37249639 x 10^-51 in kg.s (?)

All kinetic clusters are pulsatile because when they absorb and release an intercepted free elementary quantum particle at speed c, first phase, their inner energy/volumes increase at a constant outer pressure, and second phase, their inner energy/volumes decrease at the same constant outer pressure from the Quantum Space.

2. The value of electron mass in Quantum Space is given by experimentally verified formula:
me = mc e^2/4πεo re ĥ =9.10938215(45)×10^−31 kg, where: e= 1.6021765314) x 10^-19 C, is the elementary electric charge; εo= 8.854187817 x 10^-12 F/m, is the electric permittivity of Quantum-Electromagnetic Space; re =2.8179403253 x 10^ –15 m, is the average radius of pulsatile electron. The same quantitative result is obtained with wave expression of constant h:

me = mg e^2/4πεo re h =9.10938215(45)×10^−31 kg/s (?), but the error occurs because mass is expressed in kg / s.

3. Number of excitation-relaxation cycles of elementary particle quantum into Gravitational Space (subquantum factor of gravity), results from resonance equation between both the Gravitational and Quantum spaces (a form of unitary equation of the two spaces):
nc= e/(4πεoGmg^2)^1/2 = 2.521834411x10^41, where G= 6.67421 x 10^ –11 N.m^2/kg^2.
Average radius of pulsatile elementary quantum particle results from the also verified experimentally equation: rc = ncGmc^2/ĥ = 1.380669072 x 10^-36 m.

The same result is obtained with wave expression of constant h, but the error occurs because the radius is expresed in m / s: rc = ncGmc^2/h = 1.380669072 x 10^-36 m/s (?).


4. You define the quantum of photon energy by the product hvi, where the frequency vi proves that you refer to an propagated oscillation, so the energy of the waves.
We all know however, that waves of any kind, including those generated by the photon into the Quantum Space , are completely expressed only by the power ĥvi (expressed in W); the parameter "energy" is an indeterminate, depending on the time duration of measurement.
Power emission of pulsatile electron is given by the experimentally validated equation Pe = ĥve=8.187347x10^-14 W, where ve = c / λe = 1.235589973 x 1020 s^-1, is the frequency of the pulsatile electron and λe is the kinetic wavelength generated by the pulsatile electron into Electromagnetic-Quantum Space (equal to the Compton wave).
The same quantitative results is obtained with wave expression of the constant h, but the error occurs because the power will be expressed in J instead of W.
Confusion have persisted over 100 years because of equality given by resonance between the two parts of the Quantum Space: niĥ= hvi, . Number of corpuscular quantum collisions per second is equal to the frequency of waves generated by the particle / photon into the Quantum Space.

5. Based on results from the new Physics of the Corpuscular-Wave Spaces, an experience is shown in attachment where the heat is captured from the air and converted directly into cold, as an active solution against global warming, and a possible new source of energy in the future.

Cordially,
Iulian Somacescu
